The Gunners required a very late goal from the returning Danny Welbeck to beat Premier League leaders Leicester City 2-1 at the Emirates Stadium on Sunday but it was by no means a dominant performance.
Arsenal fell behind to Jamie Vardy's 45th-minute penalty before Danny Simpson was sent off for a second bookable offence early in the second half. That set up man entertaining end which saw Theo Walcott equalise prior to Welbeck's late winner but Gunners legend Henry was not all that impressed by the performance of Arsene Wenger's men.
"The ending was just like a great movie. Arsenal didn't do enough to win the game at the end of the day, I thought," he said on Sky Sports.
"Leicester obviously went down to 10 men which made it easier for Arsenal to play - and what a finish!
"[Arsenal] have difficult away fixtures and they had to win today. I don't think they played really well, I don't think that was a great Arsenal. They didn't look like champions but they won the important one."
